Speaker comments: Bot got a double right answer off a single prompt, wasn't sure how to feedback that without confusing it so I ignored it. I've been trying to tell it when it gets a right answer off a wrong prompt, but it got the one I meant and a second, unrelated shape I wasn't trying to describe, no idea how to approach that, sorry.
